because in the “main” test administered by the Fukushima prefectural government, none exceeded the stringent national provisional safety limit of 500 becquerels/kg of radioactive cesium.

The highest was from a district in Nihonmatsu City, 470 becquerels/kg (page 9 of the linked PDF file). But not to worry, rice farmers of the particular district. The Fukushima prefectural government will buy up all your rice, according to Kyodo News English (10/12/2011), probably using the money from the national government (i.e. nation’s taxpayers’ money).

It’s a win-win for Fukushima rice farmers who went ahead and grew rice. If tested for less than 500 becquerels/kg of cesium, they are all set to sell. If tested close to 500 becquerels/kg, the government will buy the crop. No information on what the prefecture is going to do with the rice it buys up, but I suspect it will find its way to the market eventually. It’s a lose-lose for a minority of conscientious farmers in Fukushima who chose not to grow at all this year – no sales, no compensation. Good luck, consumers, finding radiation-free rice and fighting critics who tell you that you are selfish on insisting on clean food.

Diary of my temporary return to Iitate-mura in early October: The result of the radiation test for the rice came in. Surprise, surprise. 2,194 becquerels/kg [of radioactive cesium] in brown rice, more than 4 times the provisional safety limit. Since it was so high I arranged for the re-testing, just in case. As to the rice crop in the rice paddy, it has to be mowed down by the end of this week. So the new crop of rice will be feeding the wild boars.

He had said in his earlier tweets that when he had to leave the village in spring, he sprinkled the seed rice on his rice paddy and let the nature take its course instead of throwing it away. To his great surprise, the rice thus sowed directly (as opposed to planting carefully cultivated seedlings) and grown without any fertilizer or pesticide and without any tilling grew better than ever. He duly noted the irony, but also now says, “If I ever grow rice again, I will do the direct sowing and do none of the maintenance work. The traditional way of growing rice by planting seedlings, using fertilizer and pesticide, tilling, weeding and other constant care is nothing but a conspiracy by the agribusiness and JA (agricultural producer co-op).”

Way to go, farmer A1271. I hope you can get to grow crops again somewhere cleaner.

… these are not “dosimeters” but “glass badges” that passively collect radiation information. It won’t help these children or their parents to avoid high-radiation areas and spots, it won’t tell them how much radiation they will have been exposed unless they are sent in to a company to interpret the data.

Radiation exposure is increased by a factor of a trillion. Inhaling even the tiniest particle, that’s the danger.

Yo: So making comparisons with X-rays and CT scans has no meaning. Because you can breathe in radioactive material.

Hirose: That’s right. When it enters your body, there’s no telling where it will go. The biggest danger is women, especially pregnant women, and little children. Now they’re talking about iodine and cesium, but that’s only part of it, they’re not using the proper detection instruments. What they call monitoring means only measuring the amount of radiation in the air. Their instruments don’t eat. What they measure has no connection with the amount of radioactive material.

Dr. Helen Caldicott (Co-founder of Physicians for Social Responsibility):

You’ve bought the propaganda from the nuclear industry. They say it’s low-level radiation. That’s absolute rubbish. If you inhale a millionth of a gram of plutonium, the surrounding cells receive a very, very high dose. Most die within that area, because it’s an alpha emitter. The cells on the periphery remain viable. They mutate, and the regulatory genes are damaged. Years later, that person develops cancer. Now, that’s true for radioactive iodine, that goes to the thyroid; cesium-137, that goes to the brain and muscles; strontium-90 goes to bone, causing bone cancer and leukemia. It’s imperative … that you understand internal emitters and radiation, and it’s not low level to the cells that are exposed. Radiobiology is imperative to understand these days.”
